New approach to show how ghost-like neutrinos helped shape the Universe — ScienceDaily

Computer simulations have struggled to capture the impact of elusive particles called neutrinos on the formation and growth of the large-scale structure of the Universe. But now, a research team from Japan has developed a method that overcomes this hurdle.

In a study published this month in The Astrophysical Journal, researchers led by the University of Tsukuba present simulations that accurately depict the role of neutrinos in the evolution of the Universe.

Why are these simulations important? One key reason is that they can set constraints on a currently unknown quantity: the neutrino mass. If this quantity is set to a particular value in the simulations and the simulation results differ from observations, that value can be ruled out. However, the constraints can be trusted only if the simulations are accurate, which was not guaranteed in previous work. The team behind this latest research aimed to address this limitation.

Future of The Downs takes shape as racing era ends

SCARBOROUGH — Less than three years after local businessmen bought Scarborough Downs and hundreds of acres around the horse track, their $621 million mixed-use redevelopment is advancing at a steady pace – despite some pieces delayed by the COVID-19 pandemic.

Nearly 140 housing units have been built and sold or leased, and more than 180 additional residences are under construction. In the planned light-industrial park, 18 of 54 lots have been sold or are under contract, two buildings have been completed and four are under construction.

But plans to build a community recreation center for the town and an operations center for Wex Inc. have been put on hold because of the pandemic, although both are still features of the town center that the developers intend to build where the harness-racing facility now stands.

“They’re on COVID hold,” said Rocco Risbara, lead developer of The Downs. “But a lot is

In New York’s East River, a tidal power project takes shape

This image shows the three turbines from Verdant Power’s Roosevelt Island Tidal Energy project, located in New York’s East River.

Over the years, New York City’s East River has been commemorated in song, provided iconic shots for movies and even inspired the composition of poetry.

From ferries taking commuters to and from work to larger ships transporting cargo, this body of water — a tidal strait which has suffered greatly from the effects of pollution over the years — can be a bustling hive of activity.

For a good while now, it’s also been home to a scheme focused on the development of tidal power, a form of renewable energy which could have an important role to play in the years ahead.

Verdant Power’s Roosevelt Island Tidal Energy (RITE) project, as it’s known, has been in development since 2002. Towards the end of October, the initiative took another

Direct visualization of quantum dots reveals shape of quantum wave function — ScienceDaily

Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.

The results, published November 23 in Nano Letters, provide important fundamental knowledge needed to develop quantum information technologies based on bilayer graphene quantum dots.

“There has been a lot of work to develop this system for quantum information science, but we’ve been missing an understanding of what the electrons look like in these quantum dots,” said corresponding author Jairo Velasco Jr., assistant professor of physics at UC Santa Cruz.

While conventional digital technologies encode information in bits represented as either 0 or 1, a quantum bit, or qubit, can represent both states at the same time due to quantum superposition. In theory,

Genes that give plant nucleus its shape discovered, also regulate copper tolerance — ScienceDaily

Researchers at the University of Tokyo have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the expression of many genes simultaneously.

The long strands of DNA and the protein machinery needed to turn gene expression on or off are contained, floating within the nuclei of cells. The nucleus is essentially a sack made of a flexible, double-membrane envelope that is supported by an inner, fine-mesh frame of proteins called the nuclear lamina.

“DNA does not drift aimlessly within the nucleus. We expect that there is nonrandom spatial positioning of genes around the nuclear lamina,” said Professor Sachihiro Matsunaga who led the research project from the University of Tokyo Graduate School of Frontier Sciences, recently published in Nature Communications.

Gene regulation is often studied at the one-dimensional level

How China could shape the future of technology

But these challenges seem unlikely to dissuade other Chinese tech companies from following TikTok’s lead, says Lin. “I do believe Chinese companies will become even more ambitious and stronger in the coming years,” he says.

He also expects these companies to increase their global ambitions: since the Chinese domestic tech market is highly saturated, with strong levels of competition, they may see more opportunities coming from the overseas market.

Changing Western tech

Already, the way Chinese-launched apps interact with users, and the services they offer within the apps, are influencing Western platforms. One example: the “superapp”.

“In China it’s very common to become a superapp, where you do a lot of different things within the same app,” says Fabian Ouwehand, founder of Many, a Dutch social marketing agency that advises companies and influencers on how to use TikTok and its Chinese version, Douyin.

Apple’s app-security tech Gatekeeper caused all kinds of problems last week, but here’s why your Mac would be in far worse shape without it

  • The surge of downloads for Apple’s latest version of macOS Big Sur caused an issue with Apple’s servers that triggered a bug in the company’s Gatekeeper.
  • Gatekeeper is the service that confirms that a piece of software is legitimate before it’s downloaded — when it stopped working, apps didn’t open.
  • Gatekeeper, and its failure, can be an annoyance for those who don’t want Apple regulating what they download, but most people would argue it’s better to be safe than sorry.
  • “Security always includes a tradeoff between convenience and protecting a user, sometimes from themselves,” says columnist Jason Aten.

Thanks for the memories: how flash changed your world (and could shape the future)

That’s a big ask, and it’s why the type of memory your devices use is a very big deal. Talk all you want about the lightning speed of your laptop processor, or the heavyweight punch of the latest graphics card, but if you don’t also talk about storage memory you’re missing a huge part of the picture. Computer storage doesn’t just save your data, it retrieves it when you want to use it again, and how quickly and accurately it can do that makes a huge difference to your viewing, playing or working experience.

A history of innovation

Which is why, 20 years ago, Samsung put its faith in what was, back then, a limited and expensive storage technology that was considered a bit, well, niche. The company had been experimenting with the predecessors of what would become flash memory since the early 1980s, even though real world applications for
